IN PROVE-4M ENT IN LANTERNS.

d iecification forming part of Letteis'Patent-No 207,104,dated l-lugust 20, 1878; application filed June 24, 1878.

To an whom. it may concern.- p s y Be it known that I, EVAN F. CASH, of Bell aim, in thecounty of Belmont and State of Ohio, have invented a newand useful Im provement in Lanterns; and 1 do hereby declare that the following is a full and exact deseription of the same, reference being had to the globe, and between the-same and one or more vertical plates of proper shape placed against the globe; in making the globe with 'one or more grooves on its exterior, which are inclosed by the'vertical plate or plates; in joining the plates which form the air-passages to the base and the top, the plates supporting the top and doing away with the necessity ofpro- 'viding the lantern with a guard; in the man A ner of connecting the peculiarly-formed airpassages to the interior of the cone; and, further, in the various combinations of the several parts of the lantern, all as fully here-V- inafter explained.

In the drawings,.Figure l is a perspective view of the globe Fig. 2, an elevation of the lantern with the globe mounted therein; Fig. 3, a sectional view'of the same on the lineof the air-passages; and Fig. 4, a view of the bottom of the lantern, showingthe hinged connection of the supporting-plate with the burner.

Like letters denote corresponding parts.

The globe A may be-made in the ordinary curved or bulged form, or of any convelrtent shape. It has one o'r-more exterior greoves, a a formed in it, extending throughoutthe length of theglobe. Two grooves are preferably used, and are situated on opposite sides of the globe. These grooves make air-passages, as will be presently described. They can be blown in the globe, and consequently the globes can be made much cheaper than where tubes are pressed in them for the same purpose; a

i by sliding it upwardly.

Thegrooves d a, .of any proper form in crosseseetion, may be wholly in the walls of the globe, projecting into the same, and not to be removed from the lantern and fromcon-- tact with the plates which cover the grooves The grooves a a are covered, when mounted in the lantern, by straps or narrow platesB B, which are rigidly connected at their lower ends to the sides of the supporting-plate 0, upon which the globe rests. Theseplates extend upwardly close against the grooves in the globe, covering the same, and support at their upper ends the top 1) of the lantern, to which the bail or handle D is attached.

The top D is hinged to one of the plates B B, and locks with the upper end of the other plate by. means of a spring-cat'cln b. The I plates .13 Bjare of suflicient widtli'to coverthe grooves in the globe, and in cross-section may be flat,,with inwardly-turned edges, or may be in the form of half-tubes. Openings 0 c are made through the deflector E, leading, when the top is secured, down into the air-passages.

formed by the. grooved globe and the plates. These openings supply the air to feed the flame, and may be covered by hoods 0 c, to prevent the disturbance of the air circulation by the blowingof the wind through the openings.

The air-holes 00 through the deflectorcan be dispensed with byshortening the airpas sages at the top one-quarter -5,) of an-inch or niore and allowingthe air to enter them below the deflector. The cone F is secured centrally to the supporting-plate O, and horizontal airtubes d d are secured to the under side of the supporting'plate, connecting the air-passages at the lower ends of the plates B B with the interior of the cone. It is evident that the air-passages down the side of the globe maybe connected with the interior of the cone by tubes above the supair to the flame'around the cone.

the'upper portion of the lantern can be turned back to trim and-light thewiok. A springcatch, g, holds the supporting-plate down upon the burner. v The oil-reservoir H, which forms the base upon which the lantern sits, is at tached to the burner preferably by screwthreads, and the oil-reservoir is filled by re moving the burner; or it may be providedwith a screw-plug for that purpose.

When. the globe is in the lantern, the wick. lighted, and the supporting-plate locked to the burner, an upward draft will be created by theflame in the globe. To supply this draft' andfeed the flame, air will be drawn through the openings 0 0 down through the air-passages on' the sides of the globe, and then through the tubes dd, into the interior of the cone. Atthe same time air will be drawn through the perforations e on..the outside of the cone, the said currents balancing each other.-

The lantern,'- as thus constructed, can be moved violently or carried where the wind is blo'wingwithout being extinguished. It is also "very simple, and is cheap to manufacture.

' It will bereadilyunderstood that the grooves in the globe could be dispensed with, and the air-passages formed by making the plates B. .Bin cross-section of semicircular or other bulgingform and placing them directly against thefsides. of the globe. With this construcpurpose set forth.

tion, as where the grooves are provided, the globe constitutes a portion of the air-passages.

What I-claim as myuinvention is- 1. 'In-a single-globe'lantern, the passage orpa-ssagesfor feeding air toithe flame, situated between the outside of the globe, and a vertical plate or plates placed against the same, substantially-as and for the 'purposeset forth. v p

2'. The lantern globe A, having one ormore V exterior grooves, a a whichare constructed to form air-passages when the globe is mounted in the lantern, substantially as and for the purpose set forth. r

3. 1n a-lahtern, the combination of the grooved globe with vertical plates= covering such grooves, substantially as and. for the purpose set forth. 4. In a lantern, the plates B B, forming part of the air-passageand s'upportingthe top D, substantially as descnibed and shown.

5. In a lantern, the combinationof the grooved globe A, supporting-plate 0, plates B B, and top D, substantially as andfor the 6. In alantern, the combination, with the plates B B, forming part of the air-passages, of the top D, hinged to one plate and secured by a spring cateh to the other, substantially as described and shown.

7. In a lantern, the, combination of the grooved globeA and plates B B, supported on the plate 0, carrying the cone and hinged to theshell of the burner, substantially as described and shown.

This specification signed and witnessed this 12th day .of June, 1878. EVAN r. CASH."
